Dye Sensitized Solar cells (DSSC) with touchscreen capacitive layer from red dragon fruit.

The improvement of Information Communication and Technology (ICT) affects the demand for electricity. Dye-Sensitized Solar Cells (DSSC) is an alternative for electricity supply. Research on organic dyes and capacitive touchscreen layers has been interesting recently. In conventional, Capacitive touchscreen layers use an Indium Tin Oxide (ITO) as a channel. Replacing the ITO substrate with an organic material for capacitive touchscreen coating is a promising approach. In addition to low cost, organic dyes have an efficiency of up to 0.86%. Compared to the efficiency of conventional DSSC (2-3%), this value is not bad. Research on organic dye is also in line with the concept of sustainability and environment friendly. In this work, organic dyes were extracted from red dragon fruit (Hylocereus costaricensis). Extraction of red dragon fruit was carried out by maceration method with distilled water and the addition of citric acid. The TiO₂ layer was deposition by slip casting method. The results showed that red dragon fruit extract contained anthocyanins from phytochemical screening tests and UV-Vis spectrophotometers. [ABSTRACT FROM AUTHOR]
